Abstract

Call admission plays a significant role in providing the desired Quality of Service (QoS) in wireless networks. In this paper, we present a Guard Channel Allocation with Channel Borrowing Scheme (GCA-CBS) which manages the new calls and handoff calls and utilizes the available channel efficiently. The proposed scheme allocates fixed number of guard channels for handoff calls. New originating calls in the cell coverage area also use these guard channels if it is free. The handoff calls preempt these channels from the new calls when it is required. Our basic idea is to allow Guard channels to be shared between new calls and handoff calls. This approach maximizes the channel utilization. The simulation results prove that the channel borrowing scheme improves the overall throughput.
